Description

  The present invention relates to a knitting method in which a 2 × 1 rib structure can be increased or decreased by a flat knitting machine.

  In molded knitting that widens or narrows the knitting width, the knitting width is increased or decreased by transferring the stitches by transferring and racking. Document 1 shows a method of sequentially moving outward one stitch at a time from a stitch located outside the knitting width when forming an increase in a rubber (rib) knitted fabric. In order to increase the number of stitches, the number of wales at the end of the knitted fabric is moved to the outside of the knitting width. Also in the reduction, there is an internal reduction in which the stitch row of the appropriate number of wales at the end of the knitted fabric is moved inward of the knitting width. In either case, it is necessary to move the stitch row. In the case of Document 1, since there is no empty needle for the stitch row to be moved, it is not possible to move all at once, and it is necessary to transfer stitches one by one. is there. That is, it is necessary to transfer the stitch row.

  With 1x1 ribs and 2x2 ribs, there are empty needles in the needle bed facing the stitches that are locked to the needle bed in terms of the structure, and the stitches can be transferred together as a stitch row using the empty needles. Good increase and decrease can be done. However, with the 2 × 1 rib, there are no stitches for the stitches facing the stitches that are locked to the needle beds, and in the case of increasing the number of stitches, the stitches located outside the stitch width are the same as in Reference 1. It is necessary to perform a method in which the needles are sequentially moved outward one by one using the empty needle. In the case of decreasing the number, it is necessary to prepare an empty needle by providing a double stitch and to move inward one by one using the empty needle.

FIG. 5 shows the steps of performing a conventional one-by-one transfer with a 2 × 1 rib structure. S0 to S5 are knitting steps. In the figure, the stitches indicate knitting needles, A to D indicate stitches having a basic pattern of 2 × 1 rib structure, the black dots indicate empty needles, and the white circles indicate stitches to be locked. A line connecting the stitches indicates a crossover thread, an arrow indicates a transfer, and numerals 1 to 3 indicate the first needle, the second needle, and the third needle of the front and rear needle beds, respectively, and a configured needle group 6 Is surrounded by a thick line. These displays also apply to FIGS. When the needle group 6 is one pattern of 2 × 1 ribs, when moving one pattern, it is necessary to transfer four steps from S1 to S4 for each needle to be increased or decreased. Considering to improve the appearance of the pattern by increasing or decreasing the inside (decreasing the connection), it is necessary to increase or decrease in increments of 3 stitches of the 1st, 2nd, and 3rd needles that make up one pattern. There is. For example, when the reduction is performed on the inner side of the 5 patterns from the end, it is necessary to reduce the number of 4 steps (for 1 stitch) x 3 stitches (for 1 pattern) x 5 patterns, and transfer 60 courses in one knitting course. End up.
An object of the present invention is to provide a method in which the increase or decrease of the 2 × 1 rib structure can be efficiently knitted by transferring stitches in units of stitch rows using empty needles and reducing the transfer course.

The knitting method of the present invention is a knitting method for increasing or decreasing a 2 × 1 rib structure using a flat knitting machine having a pair of front and rear needle beds and capable of transferring and racking between the front and rear needle beds. The stitches A, B, C, and D constituting the basic pattern of the 2 × 1 rib structure are used as the first needle of the front needle bed among the needle group consisting of a total of six needles of three needles on the front and rear needle beds. When the stitch D is arranged on the needle, the stitch B is arranged on the first needle of the rear needle bed and the stitch C is arranged on the second needle, and the second needle of the front needle bed and the third needle of the rear needle bed are made empty needles, this basic The pattern is repeatedly arranged with respect to the needles in a predetermined section on the needle bed, and an arbitrary stitch position in the section is defined as an inner increase or decrease boundary, and includes the following steps on either side of the boundary And
When stitch A and stitch D are in the first group and stitch B and stitch C are in the second group, the transfer of either one of the groups is preceded by using the empty needle of the needle group including the basic pattern. Each of the stitches to be transferred sequentially performs a single reciprocating transfer, and moves to the adjacent knitting needles locked before the transfer.
A step of transferring the other group and sequentially transferring the stitches to be transferred to the adjacent knitting needles locked before transferring the stitches.

In the knitting method of the present invention, when the transfer order of the first group is set to stitch A and stitch D, the transfer order of the second group is set to stitch C and stitch B,
When the transfer order of the first group is stitch D and stitch A, the transfer order of the second group is stitch B and stitch C.

  According to the knitting method of the present invention, it is possible to reduce the transfer course by repeating transfer of a plurality of stitches at the same time for each stitch of the basic pattern using an empty needle. Reduction can be performed.

  Furthermore, according to the knitting method of the present invention, the order of group transfer is set to stitch C and stitch B for stitch A and stitch D, and stitch B and stitch C for stitch D and stitch A. The amount of movement can be reduced, and the tensile load on the knitting yarn can be reduced.

The basic pattern of 2x1 rib structure of the Example of this invention is shown in the state developed on the needle bed. It is a figure which shows roughly the knitting step at the time of knitting Example 1 of this invention with a flat knitting machine. It is a figure which shows roughly the knitting step at the time of knitting Example 2 of this invention with a flat knitting machine. It is a figure which shows the outline of the conventional knitting step.

  Next, preferred embodiments of the present invention will be described in detail with reference to the drawings. In this embodiment, the back needle bed is rackable to the left and right, and is a two-bed flat knitting machine capable of transferring between the front and back needle beds, and has a 2 × 1 rib structure having an inner increase and an inner decrease as shown in FIG. An example of knitting the body 10 having the following will be described.

  FIG. 1 shows a body having a 2 × 1 rib structure. Knitting from the hem 16 toward the shoulder 17 and in the middle of the knitting, it is possible to increase / decrease the knitting width and the 2x1 rib structure that extends in the diagonal direction and the darts with the increased or overlapped part in the part where the inner increase or decrease is performed And The darts 11 and darts 13 on the line XX are due to internal reduction, and the darts 12 and darts 14 on the line YY are due to internal increase.

  FIG. 2 shows a state on the needle bed by arranging a plurality of basic patterns 5 of 2 × 1 rib structures. Numbers 1 to 3 shown in the figure indicate the first needle, the second needle, and the third needle of the front and rear needle beds, respectively, and the configured needle group 6 is surrounded by a thick line. A to D indicate stitches constituting the basic pattern of the 2 × 1 rib structure, and the needle group 6 in which the stitches A to D are laid out is continuously arranged on the needle bed.

  FIG. 3 is a diagram schematically showing steps of knitting a knitted fabric including the dart 11 on the line XX shown in FIG. The notation in the figure is the same as that in FIG. 5. In addition, the black circle indicates a newly formed stitch and the double circle indicates a double stitch. The number of stitches used for explanation is smaller than the actual number.

In FIG. 3, stitches A, B, C, and D, which are basic patterns, are knitted sequentially from the left end, and knitted as the first pattern, the second pattern, the third pattern, and the fourth pattern in order from the left. Yes. A stitch row that moves up to the stitch D of the second pattern is used, and a stitch row that does not move to the right side of the stitch A of the third pattern is used.
In S0, the first pattern to the fourth pattern are knitted by sequentially feeding the stitches A, B, C, and D of the basic pattern in the right direction. In this case, there are a stitch A and a stitch B that face each other, and the needle bed is knitted with the needle bed shifted to the right after 0.5 needles so as not to interfere even if the needles are used simultaneously. In S1, the stitch C on the rear needle bed is transferred to the empty needle between stitches A and D. In S2, the rear needle bed is racked to the left by one needle (1P) with respect to the front needle bed, and the stitch C transferred to the front needle bed in S1 is an empty space immediately to the right of the position of the rear needle bed before the movement. Move it back to the needle.

  In S3, 2P racking is performed to the right, and the stitch B on the rear needle bed is transferred to the empty needle between the stitches A and D. In S4, 1P racking is performed to the left, and the stitch B of the front needle bed and the stitch A transferred in S3 are transferred to the empty needles of the rear needle bed. In S5, 1P racking is performed to the right, and the stitch A on the needle bed after the transfer in S4 is transferred to the left side of the stitch D on the front needle bed. In S6, 2P racking is performed to the left, and the stitch D on the front needle bed is transferred to the empty needle between the stitches C and B on the rear needle bed. When transferring the stitch D of the second pattern to the rear needle bed, the stitch B of the third pattern does not move but is locked to the knitting needle, and the stitch B of the third pattern overlaps the stitch D. As a result, stitches are reduced by one stitch.

  In S7, 1P racking is performed to the right, and after transferring in S6, the stitch D in the needle bed is transferred to the empty needle in the front needle bed. Even when transferring the stitch D of the second pattern, the stitch A of the third pattern that does not move is locked to the knitting needle, and overlaps with the stitch D, thereby reducing the stitch by one stitch. At this stage, each stitch of the first pattern and the second pattern is moved by one needle in the right direction to complete the reduction of one stitch in the front and rear. In this series of stitch transfers, each stitch performs one reciprocal transfer between the front and back needle beds, and the forward and backward steps are continuous. Since the number of empty needles that can be transferred is limited, avoid using the empty needle as close as possible to the stitch to be transferred and returning to the basic pattern position as soon as possible to prevent crossover yarns from crossing and impairing their appearance. Yes. The transfer order of the basic pattern is stitch C, stitch B, stitch A, stitch D, and stitch C and stitch B, stitch A and stitch D on the same needle bed are continuously performed.

  In S8, the knitting is performed from the stitch D of the fourth pattern toward the stitch A of the first pattern. The stitch A and stitch B of the third pattern disappear, and the movement is one needle in the right direction. After that, as in S1 to S7, the reduction of one stitch before and after each of the 7 steps is performed twice. By this series of transfer, in S9, a double stitch is formed as the second reduction, and the second pattern stitch D is reduced by one, and in S10, the second pattern stitch C is set as the third reduction. One eye is reduced. By reducing the amount of each of the three stitches before and after, one pattern of the 2 × 1 rib can be reduced, and the pattern in which the three patterns become two patterns can be reduced without being broken.

FIG. 4 is a diagram schematically showing a knitting step when knitting the dart 12 on the line YY shown in FIG. 1, and shows an internal increase forming an increase. The contents overlapping with those of the first embodiment are simply shown and may be omitted in some cases. The notation in the figure is the same as that in FIG.
S0 is configured under the same conditions as in the first embodiment. The first pattern to the fourth pattern are knitted by sequentially feeding the stitches A, B, C, and D of the basic pattern in the right direction. In S1, the rear needle bed is racked 1P to the right by one needle with respect to the front needle bed, and the stitch B of the rear needle bed is transferred to the empty needle between the stitches A and D. In S2, 1P racking is further performed to the right, and the stitch B transferred to the front needle bed in S1 is transferred back to the empty needle adjacent to the left of the position of the rear needle bed before the movement.

  In S3, 2P racking is performed to the left, and the stitch C on the rear needle bed is transferred to the empty needle between the stitches A and D. In S4, 1P racking is performed to the right, and the stitch C of the front needle bed and the stitch D transferred in S3 are transferred to the opposite empty needles of the rear needle bed. In S5, 1P racking is performed to the left, and the stitch D on the needle bed after the transfer in S4 is transferred to the right side of the stitch A on the front needle bed. In S6, 2P racking is performed to the right, and the stitch A on the front needle bed is transferred to the empty needle adjacent to the left of the stitch B on the rear needle bed. In S7, 1P racking is performed to the left, and after transferring in S6, stitch A on the needle bed is transferred to an empty needle on the front needle bed. When transferring the stitches A up to the second pattern to the rear needle bed, the stitches on the right side of the stitches A of the third pattern are not moved but are locked to the knitting needles. One empty needle is formed between the three patterns of stitches A, and one stitch is moved to the left from the position of S0. In S8, the knitting from the fourth pattern stitch D to the first pattern stitch A is performed in the reverse direction of S0, but the stitches are formed on the empty needles formed in the middle to increase the stitches.

  Also in the present embodiment, after S8, the increase for one stitch before and after each of the seven steps is performed twice in the same manner as S1 to S7. In S9, the stitch provided with a hook on the empty needle in S8 is knitted to form a new stitch A, and a new hook is provided on the empty needle on the formed rear needle bed. Further, in S10, similarly, the stitch provided with the stitches on the empty needles in S9 is knitted to form a new stitch B, and new stitches are provided on the formed empty needles on the front and rear needle beds. By the next knitting, this hook becomes a new stitch C and stitch D, and the increase in the stitches of the basic pattern is completed. Similar to the first embodiment, each stitch of the basic pattern is transferred by one reciprocation between the front and back needle beds, and the forward and backward steps are continuous. The transfer order of the basic pattern is stitch B, stitch C, stitch D, stitch A, and stitch B and stitch C, stitch D and stitch A on the same needle bed are continuously performed.

  In both embodiments, the first pattern and the second pattern are moved, but more patterns may be used, and in this case, the number of steps can be increased. The movement for one stitch can be performed in a 7-step transfer course, and even if one pattern is considered, the first needle, the second needle, and the third needle that make up one pattern are in units of three stitches. This is a 21-step transfer course. Even if it moves as a stitch row for five basic patterns, it can be handled in 21 steps, and it can be knitted efficiently with a small number of transfer courses as compared with the 60-step transfer of the conventional method.

  In both examples, when the stitches A and D of the front needle bed are the first group and the stitches B and C of the rear needle bed are the second group, even if the order of the stitches to be transferred changes, It is done in groups. This is because when the opposite empty needle is used, the basic pattern is not destroyed, and the amount of racking movement is also suppressed. In the embodiment, the stitches B and C of the rear needle bed are transferred in advance, but the stitches A and D of the front needle bed may be preceded, and are symmetric in the front-rear direction as in the embodiment. Just move. Specifically, in Example 1 in which the stitch C on the rear needle bed precedes, a pattern in which racking is not performed in S1 is shown, and the stitch D on the front needle bed is transferred to the opposite empty needle, In the process, the moving direction may be reversed left and right. The transfer order is stitch D, stitch A, stitch B, and stitch C. Further, in Example 2 in which the stitch B on the rear needle bed precedes, a pattern is shown in which racking is performed in S1, and the stitches on the opposite empty needle are performed by racking the stitch A on the front needle bed on the opposite right. What is necessary is just to carry out transfer and to make a moving direction reverse right and left at a later process. The transfer order is stitch A, stitch D, stitch C, and stitch B.
